As my new plant table (here) now sits majestically in the patio off my bedroom, I'm feeling rather motivated to get some mosaic pots done to fill in some of the holes.
Old paint cans make fairly sturdy plant containers. I grouted a small one and am using up some old green floor tiles on another. I can't use any other tiles with the green one because of the thickness which explains the lack of any sort of design. I'll grout it with white cement and it will still be interesting. As I have dozens of succulents in plastic containers (they multiply when I'm not looking), there will be no end to mosaicking.
